Recently Issued Accounting Pronouncements	2. Recently Issued Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842) and subsequently issued related ASUs, which requires lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (a) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (b) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The ASU will be effective commencing with our quarter ending March 31, 2019. We will adopt the new guidance using a modified retrospective basis and anticipate applying the optional practical expedients related to the transition. Based on leases outstanding and our preliminary assessment as of September 30, 2018, we expect the adoption of this ASU to result in an increase between $45.0 million and $60.0 million to our assets and liabilities on our consolidated balance sheets with an immaterial impact to the consolidated statements of operations. In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows companies to reclassify stranded tax affects resulting from the U.S. Tax Cuts and Jobs Act of 2017 (“Tax Reform”), from accumulated other comprehensive income to retained earnings. In addition, the ASU requires certain new disclosures regardless of the election. This ASU will be effective commencing with our quarter ending March 31, 2019. We do not expect the adoption of this ASU to have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements.
